I'll be making my way back to this project very soon. To ease back into it, I'll be correcting the nacelles first.

They need to be lengthened 2" and the bows need to be reshaped. This will be done with a new buck that will accommodate the extra length and the new shape, then vacuum formed in clear so that the lights can be added in the lower nose of the nacelles. The shrouds at the top front of the nacelles will need to be reshaped as well to match the bottom profile.

Started refining the basic shape of the bridge dome and wall assembly. These two masters will be molded, then cast in clear Smooth-On Resin so they can be back-lit.

 

The aft section of the wall has a taper from its base to the top. I added a thin strip of styrene at the bottom of the wall, then applied Apoxie Sculpt to shape it, then sanded it to shape. I applied glazing filler to smooth out the assembly.

Here the taper in the aft wall can now be seen.

This expanded image to the NX Excelsior studio model's bridge shows the angle details in the leading edges of the wall. This has always been assumed to be a single angle, not three.

The Bridge Dome Master is hollowed out for lighting purposes.

Inside surface is Smoothed out.

The parts will be primed and polished so that the window/light port positions can be taped in. Several coats of primer will then be applied and buffed to build up a new surface. The tape will be removed to render all the light sources in both the dome and the wall - which has two light sources on each section of the wall.

 

Here is an image of the Studio miniature NX Dome with some light ports showing.

And here is the bridge and wall light sources being shown on-screen.

Wow! Missed this the first round. I am impressed with the work you're doing. Very professional. I've never been a huge fan of the Excelsior class ships, but they are growing on me. And seeing this one come together makes me actually start to like the shapes much more. Keep up the great work!

NEW Hi quality RARE photos of the NX version of the studio model have popped up. What was once thought to be a gap with a wall around the bridge dome has revieled that dark blue paint an low-res images has thrown off Trek modelers and Excelsior fans for decades.

 

Here, I've added strip styrene to the base of the side walls to taper the surface about 10deg. The Aft wall however is more pronounced at 20deg.

 

1030161043-1_2.jpg

 

Apoxie Sculpt has been applied to render the new surface.

 

1030161056-1_2.jpg

 

Here, Apoxie Sculpt has filled in the gap between the wall and the dome.

 

1030161120-1_2.jpg

 

Here is an image of the studio model on-screen. What we've thought to be a shadow of the wall being cast on the dome is actually Dark Blue painter hull surface.

PhotoBucket must have been doing maintenance or something, but it's working great now.

New direct image from the top of the torp launcher section.

New 68mm circle cut 10mm to the left of center axis. (more than a half circle)

Circle test fit over the image.

Confirming the scale of the image to my secondary hull master.

http://s676.photobucket.com/user/Tracy_Mann/media/0317170138-1.jpg.html?filters[user]=89213344&filters[recent]=1&sort=1&o=1

New plate placed on the master. You can see that the extended material making it more than half a circle, plus the tapered shape of the hull gives the illusion that the plate looks oval.

3D model of the aft torpedo launchers is done and in the print que.

3D printed Aft Torp Launchers arrived. Here, a size, shape, and scale check over a scaled image of the studio model.

Next, a couple of images with the part in place on the bottom of the secondary hull master. Real happy with how this came out!

A few advances towards shaping the neck/dorsal structure, and the Warp Nacelles.

 

Template for the large plates. The smaller spacer template will be made directly from this template by removing 5mm of material from the outer edge.

 

0503172001-1.jpg

 

The neck sweeps forward at a 31 deg angle as seen in the drawing at the bottom of the page. The yellow sticky depicts the size of the two torp launcher recesses.

 

0503172003a.jpg

 

The Warp Nacelles need to be lengthened 1.5" to a total length of 22" to match the scale of the primary and secondary hulls, and the bow of the nacelles are terribly inaccurate in shape. Here a template was made directly off a scaled image of the studio model, and a Lunar Models nacelle bottom is placed over it showing the shape issue. Once the length and shape are corrected, a set of templates will be made to determine the shape of the grill plates in the nacelle.

The plug to lengthen the nacelles to 22" is made from dense foam.

 

Here, the pattern is drawn in.

 

0508171536-1.jpg

 

It was cut out with a band saw, then roughly shaped before filling.

 

0508171800-1.jpg

 

Once refined, this plug will be molded, then two copies will be cast - one for each nacelle master.

Extension plug finished, molded and super glued into the nacelle.

Same paper template was used to re-shape the leading edge of the Top Bow cowl.

 

0515172344.jpg

 

Parts glued onto the  plates.

 

0516170042-1.jpg

 

Paper templates made off the studio model images were made to update the shape of the trailing edge contour of the cowl.

 

0517170006-1.jpg

 

Trailing edge thin styrene patterns cemented into place.

 

0517170011-1.jpg

 

Now the Apoxie Sculpt was applied into the extension plugs, and sculpted into place to flesh out a rough contour for the corrected shape of the nacelle's bow.

 

0517170214-1.jpg

 

Close-up of the bow sections.

 

0517170214a-1.jpg

 

I'll let the Apoxie Sculpt cure for more than a day. I injected resin into the flimsy vacuum formed upper cowl kit parts to reinforce it for vigorous sanding so they won't cave in from the pressure. The Apoxie will be worked with various sanding techniques to refine the required shape, then a multitude of filling, sanding, and priming sessions will take place to get the nacelles to the desires shape.

First round for refining the shape of the Nacelles bows. The Apoxie Sculpt has been sanded to shape.

Next, filler will be applied to cover seems and imperfections in the nacelles.

Back and forth with priming and sanding to level the surface.
